[QUOTE="bigfella350, post: 1010442, member: 81631"] Im still in the process of load testing for my 300 win mag and so far ive tested 3/4 diff charges so far and 2 diff seating depths. Anyways last night i noticed, after fl sizing all my fire formed cases, that about 15 cases didnt chamber smoothly. The bha match cases i have let the bolt close easily but the ones causimg me trouble were winchester and regular bha btass. I also noticed the. onea that chambered well were all shot using rl22 and they were all seated closer to saami specs. The ones that gave me trouble were all loaded with h1000 & were seated just .005-.010 off the lands. Im thinking over pressure mightve caused the difference but i started and stayed well below max. Also, i have a shilen match barrel thats 26" and ive had about 100 rounds thru it so far. Would the chambering in my barrel likely be tight? Ive got a neck turmer on order so if thats the case it wont be a problem to fix here soon. But im just trying to narrow down the poss causes here. Also, i measured from the shoulder to the head and got 2.20" so i bunped the shoulder back to 2.19 then 2.18" but still the same. Measured the oitside of the neck and got .22 all way around. Even tried neck sizing after fl sizing to see if thatd help and sized the neck all way down. Didnt notice a difference with this either. So im at a loss. Thanks for any help in advance [/QUOTE]
